Mechanism of action

MTBVAC is a genetically modified live vaccine derived from M. tuberculosis with deletions in two genes (RD1 and panCD) that reduce virulence while preserving immunogenicity. It is designed to induce both cellular and humoral immune responses to protect against TB infection and disease progression. The vaccine aims to provide superior protection compared to the standard BCG vaccine, particularly in preventing pulmonary TB in adolescents and adults.
